Which medication class is typically used to manage chronic asthma?

Long-acting beta agonists (LABAs) are a class of medications specifically indicated for the management of chronic asthma. These drugs work by stimulating beta-2 adrenergic receptors in the respiratory smooth muscle, leading to bronchodilation and an increase in airflow. LABAs help to provide sustained relief of asthma symptoms, typically lasting for 12 hours or more, and are often used in combination with inhaled corticosteroids for better control of asthma.

The other medication classes mentioned are not primarily used for chronic asthma management. Antibiotics are used to treat bacterial infections and would not be effective in managing asthma, which is primarily a chronic inflammatory condition of the airways. Antihistamines are typically used to manage allergic reactions and symptoms of allergies, such as rhinitis, but do not address the underlying inflammation or bronchoconstriction associated with asthma. Antiplatelet agents are used to prevent blood clots and are not relevant in the context of treating asthma. Thus, the role of LABAs in facilitating long-term control of asthma symptoms is crucial in the management of this chronic condition.
